Bold as his statement was, I don't think it was complete fiction.
Imagine a story about a new world war. For now, the world is somewhat clearly divided into two camps, white Westerners and the rest. And the Middle East could be a central area of warfare. The Islamic world faces NATO. Most of the fighters in the Islamic world are American. If the international situation deteriorates sharply in a few years, the Islamic State will face the F-35. Who can fight the F-35 then?
Therefore, for future strategic consideration, it is possible for Middle East countries to support Pakistan to contact J20, or for China to train PAF in advance to learn the air combat tactics of the fifth-generation fighter. The J20 is designed to operate over a wide area, which is more in line with future wars in the Middle East. A small number of J20 were used to defend the F-35 from simultaneous incursions from Israel, Europe, and the Arabian Sea.
I don't think J20 is for India. There is no use putting too much pressure on India at a time when it has no obvious choice.
